PRELIMINARY INFORMATION

GENERAL PRECAUTIONS

** ESD PREVENTION STEPS MUST BE USED DURING ANY MODIFICATIONS AND/OR

REPAIRS TO THIS UNIT! **

Product ESD Information

This product contains ESD sensitive components, or ‘Electrostatic Discharge’ sensitive

electronic parts. The Electrostatic discharge is defined as the transfer of charge between

bodies at different electrical potentials.

Electrostatic discharge has the ability to modify the electrical characteristics of a

semiconductor device, possibly degrading or even destroying it. Electrostatic discharge also

may upset the normal operation of an electronic system, causing equipment malfunction or

failure.

Laser Safety Information

Use of controls or adjustments or performance of procedures other than those specified

herein may result in hazardous radiation exposure. Under no circumstances should the

customer attempt to service the scanner. Never attempt to look at the laser beam, even if the

scanner appears to be nonfunctional. Doing so could result in hazardous radiation exposure.

The MS7100 Unit is rated as a CLASS IIA laser product, as defined by The U.S. Federal Laser

Product Performance Standard (FLPPS): Title 21 of the Code of Federal Regulations; Part

1000; [Parts 1040.10 and 1040.11].

Laser Classes

CLASS I, II, and IIA lasers are defined as:

• CLASS I: cannot emit laser radiation at known hazard levels (typically continuous (CW):

0.4microwatts at visible wavelengths). Users of a Class I laser products are generally

exempt from radiation hazard controls during operation and maintenance (but not

necessarily during service).

• CLASS II: low power visible lasers, which emit above Class I levels but emitting a radiant

power not above 1mW. The concept is that the human aversion reaction to bright light will

protect a person.

• CLASS IIA is a special designation that is based upon a 1000 second exposure and applies

only to lasers that are "not intended for viewing" such as a supermarket laser scanner.

These laser are emitting light in the visible wavelengths (0.4 to 0.7 mm) with power not

above 1mW.

THEORY & OPERATION

SCANNER OPERATION

Startup

When the scanner first receives power the white LED will flash, the blue LED will turn on and

the scanner will beep once (the white LED will remain on for the duration of the beep). The

scanner is now ready to scan.

Power-Up Test Mode

When a Stratos scanner is first powered up, it cycles through a number of self-tests before

starting normal operation. If there are any initial failures during this sequence of tests the

scanner will beep or razz to indicate the error and an error code will appear in the diagnostic

indicator display.

The following are examples of the types of tests performed at power-up.

1. Memory tests

2. Hardware setup tests

3. Motor tests

4. Laser tests

5. Configuration tests

6. Interface tests

These tests are also performed on a periodic basis with the operator alerted to any failures.

Programming Mode

All MS2020 series scanners have been configured at the factory with a set of default

communication protocols. Since many host systems have unique formats and protocol

requirements, Metrologic provides a wide range of configurable features that may be selected

with the use of the MetroSelect

®

Configuration Guide (

MLPN

00-02407) or MetroSet.

For a complete list of the factory default settings, refer to the Default Settings section of the

MS2020 Stratos
